Ultrasonic Cooling Meter Residential

Highest measurement accuracyULTRACOLD®T350 measures flow rate by the ultrasonic dragging principle. Two transducers alternatively transmit ul-trasonic signals in and against the direction of flow. The flow rate can be precisely calculated from the difference between the measured propagation times.

Future-orientedUltrasonic technology is an innovative, sensible and future-oriented basis for cold measurement in both economic and ecological terms. The measuring tube of the ULTRACOLD®T350 has a robust all-metal design and is fitted with the special internal profile Dura-Surface™. Interfering reflections in the measurement channel are filtered out from the outset. That makes the meter more resistant to dirt deposits. The advantages are obvious: technical superiority and no wearing parts. It is the excellent reliability that counts.

Long-life service and simple low-cost inspection and recalibrationUltrasonic measurement requires no mechanical moving part or straight pipe sections and can be installed any way around. The measuring tube itself has a robust all-metal de-sign. The cooling meter is insensitive to small particles in the water and operates silently.

Reliable operationULTRACOLD®T350 features enormous measurement dyna-mics. For this reason, the volume measuring units can be loaded up to twice the nominal load qp. The response limit remains at a constant low level during the entire calibration period.

Stored meter readingsYou will receive stored meter readings on a set day of your choice or at the end of the month. The readings for the last 15 months for cooling, volume and missing times are shown on a practical, configured display.

Generously sized displayThe displays are clearly structured and easy-to-understand, divided into an easily accessible customer area and a service area. Instantaneous values, set day values and monthly valu-es can be shown. Display of all consumption values facilitates traceability and billing.

Tailored selection – the temperature sensorULTRACOLD®T350 works with permanently connected Pt 500 temperature sensors. We can supply not only the standard sen-sor Direct Short M10 x 27.5 mm for direct installation but also 5.2 x 45 mm sensors for pockets – with cable length of 1.5 m or 5m. Installation accessories are available for the flow sensor whereas the return sensor is already mounted in the volume measuring unit.

Future-proof communicationWith the M-Bus communication you are connected to the world and can collect data from anywhere via modem M-Bus/RS232 or TCP/IP.
